I went back and seen it... there is another post real close to this with more votes. I looked at that one and seen it wasn't the same... then IDK the other one is right after that one and I guess I thought it was the same one that I just looked at.

My educated guess is that's the North Atlantic and probably on the Faroe Islands. Where mass culling of pilot whales ( called a grind) is permitted for stocking up yearly food sources for the islanders.
